Preparation
Preparations for the CT scan start the day before the procedure is scheduled to take place. read morePreparation
Preparations for the CT scan start the day before the procedure is scheduled to take place.
IV drip
Before the CT scan, you will be given an iodinated contrast solution intravenously (IV), which will later be flushed out by the kidneys. Kidney damage is a rare side effect of this contrast solution. The risk of kidney damage is more common in patients with reduced kidney function and in people who do not drink enough water. Drinking well before and after the procedure will help to prevent kidney damage caused by this contrast solution.
Try to drink approximately two litres of water a day and make sure you consume enough salt (you can drink an extra cup of broth, if necessary). Do this the day before the procedure and in the 24 hours after the procedure. You don't have to drink extra on the day of the procedure, before the procedure.
If you are on a fluid restriction diet, you can drink less. This diet is more important for your health than drinking is for the procedure.
If you experience any health issues before the procedure that causes you to lose a lot of fluid (e.g. severe diarrhoea, vomiting, or high fever), contact your attending physician or the Department of Radiology and Nuclear Medicine.
Before the contrast solution can be administered, we kindly ask that you print out and complete this checklist (checklist in Dutch) at home. If you don't have a printer, read through the questions anyway. You may have to call us before the procedure, or we may recommend having someone else drive you home afterwards.
Eating and drinking
You are not allowed to eat or drink one hour before the procedure (you may continue to take your medication as usual). We recommend having a light breakfast or lunch on the day of the CT scan.
Pregnant/breastfeeding
If you are pregnant or if you think you may be pregnant, please contact your attending physician. We will decide, in consultation with you and the radiologist, whether the procedure can be carried out as scheduled or whether it should be postponed or replaced with an alternative procedure.
If you are breastfeeding, you can continue to breastfeed your baby after the contrast solution is administered.
Allergic to ionidated contrast solution
If you are allergic to iodinated contrast solution, the procedure may take one hour longer and you may not be able to drive for 24 hours. Click here for more information about these precautions (in Dutch).
Clothing
It is more convenient for you and for us if you wear comfortable, loose-fitting clothing that is easy to slip on and off. Depending on the type of procedure, you may be asked to remove garments that contain metal.
Medication
Your attending physician may ask you to temporarily discontinue the use of certain medications. In most cases, however, you can continue taking your medication as usual. We do ask that you bring an up-to-date medical passport with you, which you can request for free from your pharmacy.
Disability
If you think you may need extra time and/or attention during the procedure due to a disability, please let us know in advance. We will take this into consideration as much as possible.
Stoma
If you have a stoma, we recommend taking an extra stoma bag with you. If you have an ileostomy, please notify the employee who brings you your water. In this case, you will be given less to drink.
During the procedure
We may ask you to remove some of your clothes. The procedure requires a contrast solution to be administered by an IV. You will be slid into the ring of the CT scanner on the examination table. read moreDuring the procedure
Depending on the body part being examined, we may ask you to remove some of your clothes. The procedure requires a contrast solution to be administered by an IV. Once the IV has been inserted, you will be slid into the ring of the CT scanner on the examination table. This tunnel is 70 cm in diameter and 50 cm deep and is where the images are taken. We may ask you to hold your breath for a CT scan of your lungs or abdomen.
The procedure takes approximately 20 minutes.

When the procedure or treatment is finished, the radiologist will assess the images. Sometimes this happens the same day, sometimes a few days later. He or she will write a report and send it to your attending physician, who will read it carefully. Your physician will use the report and any other relevant examinations to reach a conclusion. You can review your radiology report (without images) in MijnRadboud. The report will be available seven days after the radiologist submits it. In MijnRadboud, click on the tab ‘MijnDossier’ (My File) and then on ‘Uitslagen’ (Results) to see your report. Your physician will discuss the results of this report with you during your next appointment.As there may be some time between carrying out the procedure and drafting the report, we cannot guarantee that the results will be available in MijnRadboud seven days after your procedure. It takes seven days plus the time the radiologist needs to draft the report.
